Should experiment with halt at Ghatkopar. This will help providing good connectivity to Sakinaka, Airport, Andheri, Versova and all the way upto Dahisar by interchanging to Metro. This will also help improve it's occupancy as these passengers may prefer this train over DQ and Pragati Exp (Boarding a local train in Mumbai needs special skills and elite class may not have those skills). Now that this train has fast acceleration and deceleration, it will just consume the same time as local train and may not hold up other trains. The feature should be leveraged.
